| For transient phases, Bode and Nyquist diagrams, Ellipse spectrum, position plots and speed profile are available. |
| Nyquist continued to serve as a government consultant on military communications well after his retirement. |
| In 1932 Nyquist discovered how to determine when negative feedback amplifiers are stable. |
| For any outline, the total power is calculated as the sum, from 1 to n, of individual harmonic powers where n is equal to the Nyquist frequency. |
| Stability analysis of closed-loop systems using the root locus method and the Nyquist criterion. |
| Analog signals are usually low-pass filtered to remove most or all of the components above the Nyquist frequency in order to avoid aliasing. |
